Laparoscopic myomectomy (LM) is a recently developed surgical technique, and every obstetrician should be aware of its possible complications, which can occur not only during labor but also during pregnancy. We report a case of a primigravid woman who was hospitalized at 35 weeks' gestation because of irregular abdominal pain. She conceived spontaneously 3 years after LM. After a 20-h stay on the obstetrician ward due to increased abdominal tenderness and vaginal bleeding, the patient was qualified for an emergency cesarean section without any symptoms of fetal distress in cardiotocography. During cesarean section a newborn with 9 Apgar points was delivered and a rupture of the uterine wall was seen. Dehiscence of the pregnant uterus following LM is an incidental case, and can therefore be misdiagnosed. Close attention should be paid to every pregnancy in previously operated uteri as the dehiscence of the pregnant uterus can occur without symptoms of fetal distress.
